Product Description

Kindergarten Operations and Algebraic Thinking to introduce composing and decomposing numbers to 10 with objects, as well as a helpful review for First Graders working with associative properties of numbers, missing addends and partitioning.

One of five activities featured in Kindergarten Composing and Decomposing Resource with Ladybug craft

and the introduction to

First Grade Number Bonds and Balancing Equations (an in-depth resource covering OA.A1-D8).

Use as a whole class, in groups or for RTI Tier II intervention.

Students need to have a firm foundation of number bonds and building and breaking numbers before they can attempt missing addends, so to begin with demonstrate using the number bonds work mats to show how to decompose and compose numbers. If possible, project this to a whiteboard and use manipulatives to show the students how to break numbers. Give each student their own work mat and popcorn manipulatives (or use counters or real popcorn!). Start by drawing one of the popcorn number cards and place that number of popcorn manipulatives onto the circle under the elephant.

Have the children share the popcorn between the lion and the seal and discuss the different ways they found to share. Then tell the students how many popcorn kernels to give the lion and have them find how many are left for the seal. Practice this frequently – it is a great way to start every math lesson and review at the end. As children become more proficient in decomposing numbers, have them play this game and record their work.

When students have shown proficiency in breaking and making numbers, they are ready to work with missing numbers and balancing equations. Students will need lots of practice.
